OKLAHOMA CITY — The i2E Angel Sidecar Fund recently closed a $500,000 investment in Tailwind, leading a $1 million investment round in the Oklahoma City-based company. The funding also included the i2E-managed SeedStep Angels and other angel investors.

Tailwind, formerly PinLeague, is a rapidly growing software company that provides a suite of Web-based analytics and marketing tools that help major brands connect with users on the Pinterest social network. About 3,000 brands and agencies use Tailwind to track information such as brand following on Pinterest and repins.

“We’ve seen incredibly rapid growth throughout 2013,” said Daniel Maloney, Tailwind co-founder and CEO. “This funding provides us the ability to grow our team to continue supporting the larger customer base and providing the same great quality of support that our users are accustomed to receiving.”

The OK Sidecar Fund is one of three Accelerate Oklahoma! investment vehicles created in 2011 by i2E through a partnership with the Oklahoma Department of Commerce and the U.S. Treasury State Small Business Credit Initiative. The OK Sidecar Fund invests alongside angel groups and individual investors to increase the value of an investment round in an individual company.

The SeedStep Angels were founded by i2E in 2009 and now have chapters in Oklahoma City, Tulsa and Ardmore. Investments by SeedStep Angels members now total more than $4 million since the group was founded.
